Mr. H. B. Brady on some Arctic Foraminifera. 401 
mella striatopunctata contained in these soundings had origi- 
nally a thin coating of adherent sand. In all cases this sandy 
investment is easily removed, without mechanical interference 
beyond washing in warm water. Amongst the adherent arena- 
ceous types a similar tendency may be observed. Valvulina 
conica is commonly surrounded at its base by an accumulation 
of fine sand, easily distinguished from the test itself by its 
colour; and the same is the case with certain true Textularia, 
of rough arenaceous texture, when found growing attached to 
other bodies. If the shell of any of these be detached, the 
sandy environment remains behind, showing that it has no 
real connexion with the proper test. 
The following is a list of the species found, with notes on - 
some of the more interesting and important forms. The num- 
bers prefixed correspond with those in the Distribution Table.
